Our Silverado LTZ test truck featured an optional touch-screen navigation system that was simple to use and view. Small, rubber-gripped dials serve to control volume and tuning, while smaller, clearly-labeled buttons take the operator directly to the navigation system, the radio, the seek function, and other oft-requested tasks. Steering wheel controls behind the right-side spokes are provided for volume and tuning. Our truck also included a rear DVD entertainment system with a fold-down screen, rear seat controls and input jacks, and a pair of wireless headphones. The screen is placed forward far enough to allow for clear viewing for the outboard passengers. For long trips, the $1,295 system may prove well worth the investment.
